    CYT3001A

    product manual

    CYT3000A is a high power factor linear constant current high voltage LED driver chip for LED lighting applications. The chip uses a unique constant current control patent technology to achieve a constant current accuracy of less than ± 5%, and the output current can be adjusted by an external REXT resistor. The chip has high power factor and low harmonic distortion.

     

    The system has a simple structure and various protection functions, and does not require a transformer and a high-voltage electrolytic capacitor. The high-voltage LED driver chip has few external components, which can save space occupied by electronic components, and can realize batch operation of LID lighting solutions.
